Great subject and the contrast/figuring of the clouds in B/W is nice (color not so interesting) - I'm not so sure about how it is framed though. The center part of the rock formation creates a nice "U" shape and then plateaus and moves off frame to the left...this part of the formation on the left detracts from the "U" I think...and maybe too much sky/foreground. You might look at this cropped top/bottom/left - so the most interesting part of the formation becomes more prominent. /B
